- some sounds of the textballoons sound the same as in the Lufia games.

- There is a blind bluehaired girl who tells the future (I think) her name is Selfy, but when you talk to her you'll find out that her full name is Selfia. (Which is spelled セルフィア (Selufia), so that is just ルフィア (Lufia) + Se in the beginning.

- In Lufia TLR, there is a dummied item named Energy Breaker, this might be a reference to the game Energy Breaker.

-In Lufia DS, there are three shrines named Kardia, Soma and Rogisumosu shrine/temple.
Kardia is the name of the village from Rune Factory 1.
Soma is spelled the same as Sawma's japanese name. Sawma is one of the villains in CIMA The Enemy.
I don't know if Rogisumosu is a reference to something.
